  • Dithiocarboxlic acid self-assembled monolayers and methods for using same in microconact printing
    Patent number: 6890598
    Abstract: Aliphatic dithiocarboxylic acid compositions (ADTCAs) that form self-assembled monolayers (SAMs) on metal surface such as gold surfaces are disclosed. These new SAMs were characterized by optical ellipsometry, contact angle goniometry, and polarization modulation infrared reflection absorption spectroscopy (PM-IRRAS). The data indicates that the ADTCAs generate well packed and highly oriented monolayer films on gold surfaces. A method for using the ADTCAs in micro-contact printing is also disclosed, where ADTCA SAM protected regions are capable of more efficient cleaning under mild conditions due to instabilities in the ADTCA compositions.
